You missed the key advantage: heat dissipation. Currently tesla packs have liquid cooling channels winding among the batteries and heat is largely dissipated to the walls of the cell. They could not be made larger partly because the big cell would insulate the core too much. The tabless design allows heat to dissipate from the center of the cylindrical cell to the top and bottom caps (so larger diameter doesn't matter). The possibility of better, cheaper plate cooling is a big part of the longer life (not just reduced resistance) and is what unlocks the larger cells.

@Mario De Cristofaro batteries may not become mainstream when it comes to power storage in electric mobility. But do you have doubts about electric mobility becoming mainstream in transportation? If that's the case, I guess there's nothing I can say that may help you...
Electric vehicles were around in the late 1800's. We're just now figuring it out that we should have continued down that path instead of our chosen ICE option.
@Mario De Cristofaro I'd love to understand what you just said, but looking at the references you mention, I'm not so sure you understand it either... :-/ Electricity is probably the purest form of energy there is, at least that we know. Our biology uses a wide range of electric power, from micro volts (e.g., neurons) to full volts (e.g., the heart). Still, it's a lot to deal with. But two things we know: 1) for almost everything, it's the most efficient form of energy we use; and 2) the amount of energy the sun "wastes" every single day could provide for years of current human consumption. Plants have been using it for millions of years, that's why we take oil from the ground: plants store the sun's energy just like tiny batteries!

If you continue, a certain substance will refill your accumulator. Today, the more you tire yourself, the more your organism will produce this substance." Mario, if I had the conviction (like you seem to have) that there's any truth in Gurdjieff's ideas, I would make them effort to study them and understand him.

Having just bought a Leaf and had the battery changed to one with more capacity, It would be a huge advantage if Tesla batteries could be easily changed. It took my mechanic less than one hour to remove the old battery and install the new one.
that battery is so cute, actualy i drinking my tea and waiting for ver:2.0 battery generator. BCG /battery cell generator / can be smaller and generate same amount of energy per hour.
I might think Tesla is a little overvalued on a balance sheet stand point, but no other company is doing so much to keep growing and innovating. No other car company is simultaneously building a network of electric production, storage and charging to power their product line, and no other car company has the vision that Elon has. No hype or anything these guys just have the wind in their back and they are actually doing something about the issues we are facing as a society. I picked up shares at $670. Not ideal but I stand by it.
So does that mean when the batteries have expired/run out of juice/malfunctioned you throw away the car? Though i am pretty sure i misunderstood the meaning of permantly fixed.
Non-removable batteries? I would say the opposite would be ideal: you can drive into a "gas station", (let somebody) take out your empty battery, put in a full one and you're good to go! Meanwhile the battery you leave behind has all the time to (slowly) charge, which is better for the battery. Win-win.
Its still old tech - just a standard battery enlarged. Its not as cool as pouch batteries in other electric cars that are not only also quite big but also do not have the space wasting features of a round shape.
You should make a video of the current worth of your portfolio which must be alot Esp. with Tesla, I also came by an investor that made a profit of $350K within months and I'd really appreciate it you I can get clues and tips on how to make better profit.
@Clarence Vutt I have actually come across this Bonita broker before on a magazine, I google searched her and I'm definitely getting in touch with her, thanks for sharing.
All your numbers are wrong, they use gigawatts now, The pilot line for the new cells, is 10 GWh/year 1 Line. Panasonic's 11 lines in Nevada CATL?'s lines at shanghai, do a lot less but still. The new cells are not stiffer, all cylindrical cells are stiff, but they are glued into the chassis, instead of being packed into modules, then packs, then bolted on. Quicker, cleaner and cheaper. The cooling is a prime advantage, as electrons only need to travel to the top of the cell to escape, they generate little heat, and it is not concentrated. In a normal cell the electrons need to zoom around, and around and around, until they get to the tab, then squeeze through it, creating both a lot of heat from bumping things along the way, and concentrating a lot of this heat at the tab, right at the middle .... And I am sure the patent is a few years old, but it was finally granted. Panasonic is developing a line to make TESLA cells, but Tesla already producing them, and the Model Y coming out of Germany soon will be using the full cast chassis, integrated 4680 cells and all. As usual your research is for .$%&^*. Give up, or read up
And tabless is not exactly new: a similar design principle has been used for metalized polypropylene capacitors: have the electrodes stick out from opposite ends of the roll and metalize the ends to bridge layers together for sub-mOhm ESR. Multi-layer chip capacitors have been built in a similar manner since their inception too.
sounds like good news. Too bad I'd never* own a Tesla, but I'm glad they can keep competition going against other automakers. This is the direction we need to take.
I don't think so, Tesla already decreased charging time for some older models, which seems to hint at planned obsolesce - it is more profitable to make the buyer replace their car with a new one rather than make the old car last for longer
just want to clear one thing: batteries have never been permanently put into any sort of device or machine, if it is 'permanently' put into a device or machine they are put in such a way that only the manufacture could remove them which is still not really permanent
What about the weight added? An electric car is still very heavy compared to a gasoline powered car. That weight is going to consume some of that 16% of the energy increase...
Have you heard of Realfiction holding and their new technology that will revolutionize the way we watch television? in addition to being able to display holographic images, a major upside is that the technology requires 80% less electricity than ordinary displays resulting in huge savings of approximately USD 7.4bN, 1.34% of the electricity production equivalent of 56 TWh of electricity and 25 million tons of CO2 only in the United States.
We are close to using all the planets oil capacity I say close but they recon 53-70 years left.. now we can deplete all the metal and cobalt yay!!! ... Anyway haha nice car
I believe the time is coming soon where Tesla will be able to offer cars with smaller battery packs with less range because of the fact that there is more places to charge and that people start to realize that range isn't an issue anymore. This will speed up the coming of the affordable Tesla !
I can't really believe that. If a tabless battery has so many advantages, it must have significant disadvantages. There are thousands of engineers who have been working on battery development for decades. If the tabless was supposed to have advantages, the engineers and battery manufacturers would have figured it out long ago and produced it that way. So, something is not right, something is being concealed.
You missed the key advantage: heat dissipation.

that battery is so cute, actualy i drinking my tea and waiting for ver:2.0 battery generator. BCG /battery cell generator / can be smaller and generate same amount of energy per hour.
the vids be amazing keep it up man
So when and where is Tesla going to build its first battery factory? Indonesia???
Did yone else just randomly find this video and say oh ok
@wall boi lol
I'm not sure, but I think they will also lose less range during winter
@5:15 Wrong numbers
Please reupload with correct numbers
We are lucky to have people like Elon in our world.
How much more copper is used for this battery pack?
Start at 1:14 all that prior is pointless.
Good job, Nice info.
except for everything that was wrong and poorly informed
At around 5:18, KWh units, wrong....
Just watched a video about solid state batteries by Samsung. I think that’s where we’re going eventually.
I might think Tesla is a little overvalued on a balance sheet stand point, but no other company is doing so much to keep growing and innovating. No other car company is simultaneously building a network of electric production, storage and charging to power their product line, and no other car company has the vision that Elon has. No hype or anything these guys just have the wind in their back and they are actually doing something about the issues we are facing as a society. I picked up shares at $670. Not ideal but I stand by it.
what do you think about the solid state battery ? toyota annouced 500 miles range and 10 min for 80% charge
This guy has a tenuous grasp on tesla in general so i wouldnt expect any insights from him
toyota is all hype.
It will be another nail in Tesla's coffin.
Bro they need to sell electicity thats why
How much do they weigh?
So does that mean when the batteries have expired/run out of juice/malfunctioned you throw away the car? Though i am pretty sure i misunderstood the meaning of permantly fixed.
the cells will outlive the car, so they are likely to be re used, re sold, or recycled.
Did you not watch the video?
@@noahno did you not read what i have written?
Non-removable batteries? I would say the opposite would be ideal: you can drive into a "gas station", (let somebody) take out your empty battery, put in a full one and you're good to go! Meanwhile the battery you leave behind has all the time to (slowly) charge, which is better for the battery. Win-win.
2:25 - I just do not understand this. 5x more energy capacity, but 16% more range? How does that work??
I think in the last 5 years at least 20 batterys were announced that would revolution the world
Its still old tech - just a standard battery enlarged. Its not as cool as pouch batteries in other electric cars that are not only also quite big but also do not have the space wasting features of a round shape.
EEVBlog explained 6 months ago very precisely . It's just less than 10 % improvement. No batteries chemistry changed.
And here i am watching this on my phone with 20 year old tech
You should make a video of the current worth of your portfolio which must be alot Esp. with Tesla, I also came by an investor that made a profit of $350K within months and I'd really appreciate it you I can get clues and tips on how to make better profit.
Learn how to trade stocks.
Just do your research and devise a strategy or better still reach out to a professional for help
@Clarence Vutt Most people actually gets in touch with a professional but they wouldn't mention it
@Clarence Vutt I have actually come across this Bonita broker before on a magazine, I google searched her and I'm definitely getting in touch with her, thanks for sharing.
the tip for better profit, would be to short Xpeng, it is going to 20 dollars within 2 weeks maximum
All your numbers are wrong, they use gigawatts now, The pilot line for the new cells, is 10 GWh/year 1 Line. Panasonic's 11 lines in Nevada CATL?'s lines at shanghai, do a lot less but still. The new cells are not stiffer, all cylindrical cells are stiff, but they are glued into the chassis, instead of being packed into modules, then packs, then bolted on. Quicker, cleaner and cheaper. The cooling is a prime advantage, as electrons only need to travel to the top of the cell to escape, they generate little heat, and it is not concentrated. In a normal cell the electrons need to zoom around, and around and around, until they get to the tab, then squeeze through it, creating both a lot of heat from bumping things along the way, and concentrating a lot of this heat at the tab, right at the middle .... And I am sure the patent is a few years old, but it was finally granted. Panasonic is developing a line to make TESLA cells, but Tesla already producing them, and the Model Y coming out of Germany soon will be using the full cast chassis, integrated 4680 cells and all. As usual your research is for .$%&^*. Give up, or read up
I don’t really like electric cars but I am intrigued
It’s nice to see innovation in an industry that loves to repackage old tech and call it “new”
And tabless is not exactly new: a similar design principle has been used for metalized polypropylene capacitors: have the electrodes stick out from opposite ends of the roll and metalize the ends to bridge layers together for sub-mOhm ESR. Multi-layer chip capacitors have been built in a similar manner since their inception too.
sounds like good news. Too bad I'd never* own a Tesla, but I'm glad they can keep competition going against other automakers. This is the direction we need to take.
Aptera does the same with 4x less batteries.
140k is with FSD, or would that be 150k inclusive?
I wonder if Elon is going to offer battery upgrades to older Tesla’s
I don't think so, Tesla already decreased charging time for some older models, which seems to hint at planned obsolesce - it is more profitable to make the buyer replace their car with a new one rather than make the old car last for longer
just want to clear one thing: batteries have never been permanently put into any sort of device or machine, if it is 'permanently' put into a device or machine they are put in such a way that only the manufacture could remove them which is still not really permanent
I wonder if the 4680 is a solid state battery
What about the weight added? An electric car is still very heavy compared to a gasoline powered car. That weight is going to consume some of that 16% of the energy increase...
When will we see charging pads embedded in parking bays?
I doubt cities will ever bother to invest in something like this, unless electric cars become mainstream.
Have you heard of Realfiction holding and their new technology that will revolutionize the way we watch television? in addition to being able to display holographic images, a major upside is that the technology requires 80% less electricity than ordinary displays resulting in huge savings of approximately USD 7.4bN, 1.34% of the electricity production equivalent of 56 TWh of electricity and 25 million tons of CO2 only in the United States.
Seeing a Tesla Supercharger station makes me smile.
Why?...
How about solid state batteries
We are close to using all the planets oil capacity I say close but they recon 53-70 years left.. now we can deplete all the metal and cobalt yay!!! ... Anyway haha nice car
So we need to invest in new ways of cheaper cleaner power so we can all switch from gas to electric asap I’m investing in Tesla tomorrow
In a few days or maybe months, TESLA will announce its first "self-charging" cars. It will run perpetually to the moon and back.
non removable battery? so if it will malfunction.. whole 35.000$ car will go to the dump after e.g. 5 years?
Rush batteries like someone pointing a gun in his head, asking for weaponized robot possibility.
Amazing
LOL "Non-removable" doesn't mean "non-replaceable".... Watch me DIY that shit too lads ;)
stonks !!!!!
You really need to have someone fact check your script.
entropy will still increase
The sooner the better we will all be when petrol and diesel engines are obsolete world wide..
can't be changed by customer easily
I believe the time is coming soon where Tesla will be able to offer cars with smaller battery packs with less range because of the fact that there is more places to charge and that people start to realize that range isn't an issue anymore. This will speed up the coming of the affordable Tesla !
Permanently fixing the batteries will really hurt the batteries recyclablity in the 3rd party space
I can't really believe that. If a tabless battery has
so many advantages, it must have significant
disadvantages.
There are thousands of engineers who have been
working on battery development for decades.
If the tabless was supposed to have advantages,
the engineers and battery manufacturers would
have figured it out long ago and produced
it that way.
So, something is not right, something is
being concealed.
